Picking up after others has it's advantages.

I walk for my exercise. My walk takes me through a private club campground. They have no problem letting me use their path because they see me picking up trash every day. I will even go into the water to retrieve it. I don't do it because I can get and keep permission easier, but it's a nice perk! I fish many places that others can't. The owners know that I come out with trash that I didn't go in with.
